Birth Order and Human Capital Development:Evidence from Ecuador
Birth Order Human Capital Development Ecuador
font style='font-size:12px;'>
2016/3/3
In this paper we examine the effect of birth order on human capital development in Ecuador. Using family fixed effects models we find positive and persistent birth order effects; earlier-born children...
Direct Regression Modelling of High-order Moments in Big Data
Big data Higher-order moment U-statistics Estimating equation Divide-and-conquer

2016/1/26
Big data problems present great challenges to statisti-cal analyses, especially from the computational side. In this paper, we consider regression estimation of high-order mo-ments in big data problem...
Applications of Second-Order Cone Programming
Applications Second-Order Cone Programming
font style='font-size:12px;'>
2015/7/10
In a second-order cone program (SOCP) a linear function is minimized over the intersection of an affine set and the product of second-order (quadratic) cones. SOCPs are nonlinear convex problems that ...

2015/7/6
The approximation of a stationary time-series by finite order autoregressive (AR) and moving averages (MA) is a problem that occurs in many applications. In this paper we study asymptotic behavior of ...
High-order-mode soliton structures in two-dimensional lattices with defocusing nonlinearity
